/* If CONFIG_ARMV7M_USEBASEPRI is selected, then interrupts will be disabled
|
||||
* by setting the BASEPRI register to NVIC_SYSH_DISABLE_PRIORITY so that most
|
||||
* interrupts will not have execution priority. SVCall must have execution
|
||||
* priority in all cases.
|
||||
*
|
||||
* In the normal cases, interrupts are not nest-able and all interrupts run
|
||||
* at an execution priority between NVIC_SYSH_PRIORITY_MIN and
|
||||
* NVIC_SYSH_PRIORITY_MAX (with NVIC_SYSH_PRIORITY_MAX reserved for SVCall).
|
||||
*
|
||||
* If, in addition, CONFIG_ARCH_HIPRI_INTERRUPT is defined, then special
|
||||
* high priority interrupts are supported. These are not "nested" in the
|
||||
* normal sense of the word. These high priority interrupts can interrupt
|
||||
* normal processing but execute outside of OS (although they can "get back
|
||||
* into the game" via a PendSV interrupt).
|
||||
*
|
||||
* In the normal course of things, interrupts must occasionally be disabled
|
||||
* using the irqsave() inline function to prevent contention in use of
|
||||
* resources that may be shared between interrupt level and non-interrupt
|
||||
* level logic. Now the question arises, if CONFIG_ARCH_HIPRI_INTERRUPT,
|
||||
* do we disable all interrupts (except SVCall), or do we only disable the
|
||||
* "normal" interrupts. Since the high priority interrupts cannot interact
|
||||
* with the OS, you may want to permit the high priority interrupts even if
|
||||
* interrupts are disabled. The setting CONFIG_ARCH_INT_DISABLEALL can be
|
||||
* used to select either behavior:
